Pomegranate is a challenging fruit to process because commercial production requires more than simple juice extraction. A complete pomegranate juice processing line needs to manage fruit receiving, sorting, cracking, peel and stem separation, juice extraction, clarification, filtration, membrane processing, concentration, sterilization and final filling.
For industrial projects, equipment selection should also consider production capacity, product specifications, packaging format, cleaning requirements and the available utilities at the factory.
For a recent project configuration in Azerbaijan, the supplied technical specification includes a fruit handling and processing section designed around approximately 10–12 tons/hour of pomegranate processing, followed by clarification, ultrafiltration, concentration and aseptic filling.
This type of configuration illustrates how individual processing machines can be integrated into a complete turnkey fruit juice production system.
From Fresh Pomegranate to Juice Concentrate
A commercial pomegranate processing line generally follows a sequence similar to:
Fresh Pomegranate → Unloading → Elevating → Sorting → Cracking → Peel & Stem Separation → Juice Extraction → Coarse Filtration → Enzymation → Fine Filtration → Ultrafiltration → Vacuum Concentration → Concentrate Storage → Aseptic Filling
The exact process can be adjusted according to the required final product, such as NFC pomegranate juice or concentrated pomegranate juice.
In the Azerbaijan project configuration, the upstream fruit handling system includes a screw fruit unloading tank, Z-type elevator conveyor, modular sorting conveyor and additional conveying equipment. The main fruit handling section is specified at approximately 10–12 tons/hour.
1. Fruit Receiving and Unloading
The production process begins with fresh pomegranates being delivered to the factory.
A screw fruit unloading tank can provide a controlled method of receiving and transferring fruit into the processing line. The supplied project specification uses an AISI 304 stainless steel unloading tank with approximately 15,000 L capacity and a screw diameter of 400 mm, designed for approximately 10–12 tons/hour.
The unloading section is important because a stable fruit feed helps maintain a consistent processing rate through the following equipment.
2. Fruit Elevating and Sorting
After receiving, pomegranates are transported to the sorting area.
The sorting conveyor allows operators to inspect the incoming fruit and remove unsuitable raw materials before further processing.
The project configuration includes a modular sorting conveyor with a 1,000 mm belt width and 4,000 mm length, together with waste conveying equipment for removing rejected materials.
For commercial pomegranate processing, sorting is particularly important because damaged or unsuitable fruit can affect the quality of the downstream juice.
3. Pomegranate Cracking and Peel Separation
Pomegranates require specialized mechanical processing because the edible arils must be separated from the outer structure of the fruit.
The supplied project includes a pomegranate cracking machine with adjustable gaps and two rubber rollers. The specified processing capacity is approximately 10–12 tons/hour.
After cracking, a peel and stem separation machine is used to separate unwanted solid materials from the product stream.
The project specification describes a rotary screen and beating system with replaceable screens, including a 12–14 mm screen specification for pomegranate processing.
This combination allows the upstream system to prepare the fruit material for juice extraction.
4. Juice Extraction
After cracking and separation, the processed pomegranate material enters the juice extraction section.
The project uses a screw press with a specified pomegranate processing capacity of approximately 10 tons/hour and an expected juice yield of 85–90% under the stated configuration. The screw press uses hydraulic pressure control and an approximately 18.5 kW motor.
Actual juice yield depends on the fruit variety, maturity, raw material condition and process configuration, so the final production parameters should be confirmed through process testing.
5. Coarse Filtration and Pasteurization
Following extraction, coarse filtration can be used to remove larger suspended particles before further clarification.
The supplied system includes a rotary coarse filter with a 1 mm filter screen, approximately 625 mm drum diameter, 750 mm length and a specified capacity of 10 tons/hour.
The project also includes a multi-tube pasteurizer with a stated capacity of 10 tons/hour, heating from 65–95°C and approximately 45 seconds holding time under the specified configuration.
For different juice products, the thermal process should be determined according to the formulation, viscosity, microbiological requirements and final packaging process.
6. Enzymation and Juice Clarification
For clarified pomegranate juice production, enzymatic treatment can be incorporated before fine filtration.
The Azerbaijan project includes three 15,000 L enzymation tanks, manufactured from AISI 304 stainless steel and equipped with top-mounted agitators and CIP spray balls. The tanks are intended for juice clarification.
The process can then continue through filtration equipment.
The specified system includes a vacuum drum filter with approximately 6 m² filtration area and a capacity of 1–2 tons/hour, followed by a kieselguhr filter with a capacity of 2–3 tons/hour and a maximum working pressure of 5 bar.
The actual filtration configuration should be selected according to the desired juice clarity and product characteristics.
7. Ultrafiltration for High-Quality Juice Processing
Ultrafiltration can provide an additional separation step for juice clarification and fine processing.
The supplied Azerbaijan project specifies an UF system with a clear juice capacity of approximately 8–10 tons/hour, a membrane area of 161.84 m², 56 membrane modules and a 45 kW feed pump. Automatic CIP is also included.
The project documentation also notes that the capacity could potentially be adjusted to approximately 5–6 tons/hour, although the customer preferred a larger system because cleaning downtime could otherwise affect production continuity.
This is an important consideration when designing a commercial juice plant: equipment capacity should not only match the nominal production target but also account for cleaning and maintenance periods.
8. Vacuum Concentration of Pomegranate Juice
For concentrated pomegranate products, evaporation is a key stage of the processing line.
The supplied project uses a four-effect falling film evaporator operating under vacuum. The specified feed capacity is 8–10 tons/hour at 11–13°Brix, with a target outlet concentration of 70–75°Brix. The stated total power is approximately 85 kW, with steam consumption of approximately 2,500–3,000 kg/hour.
A multi-effect evaporation configuration is useful for industrial juice concentration because the system can recover heat between effects.
For smaller or different liquid-processing applications, a vacuum pressure reduction evaporator can also be considered where the required evaporation capacity and product characteristics are suitable.
9. Concentrate Buffer Storage
After concentration, the product can be transferred into buffer or storage tanks before filling.
The Azerbaijan project specifies two 25,000 L concentrate buffer tanks, manufactured from AISI 304 stainless steel and equipped with side agitators. The conical bottom is designed for high-viscosity products.
Proper buffer storage helps coordinate the continuous processing section with downstream filling operations.
For projects involving multiple products or formulations, storage and blending capacity should be considered together with the filling capacity.
10. Aseptic Filling for Pomegranate Juice Concentrate
Aseptic filling can be integrated when the final product requires aseptic packaging.
The supplied project configuration includes an aseptic filling system for both concentrated juice and NFC juice. The stated capacity is approximately 4 tons/hour for 70°Brix concentrate and 8–10 tons/hour for NFC juice at 6–22°Brix. The system includes sterilization and aseptic filling heads for bag or barrel packaging, together with CIP and automatic controls.
This allows the processing plant to be configured around different finished-product requirements.
11. Bottled Pomegranate Juice Production
Not every pomegranate project needs to produce concentrate.
The supplied project also includes a downstream configuration for producing bottled pomegranate juice at approximately 2,000 L/hour, using glass bottles in 330 ml, 500 ml and 1 L formats.
The downstream section includes juice and syrup preparation tanks, pasteurization, bottle feeding, rinsing, filling and capping.
The filling system is specified at approximately 1,500–2,000 L/hour, while the downstream capping system is specified at approximately 4,000 caps/hour, depending on the selected configuration.
12. Labeling, Coding and Secondary Packaging
After filling and cooling, finished bottles can enter the labeling and coding section.
The supplied project includes an automatic round bottle labeling machine with a stated capacity of approximately 2,000 bottles/hour for self-adhesive labels on round bottles.
An inkjet coding machine can then be used for product identification and production coding.
The project specification lists an inkjet coding system with up to five lines of printing and a stated capacity of approximately 12,000 units/hour.
For secondary packaging, the system also includes a semi-automatic shrink wrapping unit with an approximately 2,000 bottles/hour bottle handling capacity under the specified configuration.
13. CIP and Utility Systems
A complete juice processing plant requires more than process machinery.
Cleaning, water treatment, steam, compressed air, cooling water and electrical systems all need to be considered during engineering.
The supplied project includes a central CIP system with three tanks for alkaline, acid/chlorine and water circuits. Each tank is approximately 3,000 L, with PLC control, circulation pumps and heat exchangers.
The utility section also includes a reverse osmosis and water softening system with a stated production capacity of approximately 15 m³/hour.
A steam boiler is specified at 10,000 kg/hour steam capacity at 10 bar working pressure, while the project also includes compressed air, water booster and cooling-water equipment.

For a commercial pomegranate juice factory, the main advantages include:
- Integrated process flow from raw fruit to finished product
- Coordinated equipment capacities
- Stainless steel food-processing equipment
- Automated PLC control
- CIP-compatible processing equipment
- Juice clarification and filtration options
- Vacuum concentration for concentrate production
- Aseptic filling for concentrate or NFC juice
- Bottle filling and packaging options
- Utility and piping integration
The supplied Azerbaijan project demonstrates this integrated approach, covering fruit handling, extraction, filtration, UF, evaporation, filling, CIP and utilities within one project configuration.
Pomegranate Juice Processing Equipment Selection
The correct equipment configuration depends on several factors:
Raw Material
Fruit variety, maturity, condition and incoming capacity influence the extraction and separation process.
Production Capacity
The equipment capacity should be balanced throughout the entire production line. A high-capacity extraction section, for example, should be matched with sufficient filtration, concentration, storage and filling capacity.
Final Product
An NFC juice line and a concentrate production line require different downstream configurations.
Packaging Format
The final packaging may include aseptic bags or barrels, glass bottles or other formats. Filling and packaging equipment should therefore be selected at the project design stage.
Cleaning Requirements
CIP capability and cleaning time should be considered when determining production capacity. The Azerbaijan project specifically considers production losses caused by equipment cleaning when evaluating UF capacity.
Pomegranate Juice Production Line for Azerbaijan and International Markets
The Azerbaijan project provides a practical example of a large-scale pomegranate processing system designed around local project requirements.
The documented project location is Azerbaijan, with the processing system designed around pomegranate raw material and multiple finished-product possibilities.
For projects in Azerbaijan, Central Asia, the Middle East, Africa or other pomegranate-producing regions, the production line can be engineered around the customer’s raw material supply, target capacity, product type, packaging format and factory utilities.
Rather than using one standard machine configuration for every customer, process equipment should be selected according to the actual production conditions.
